Title: Improvements in adding and printing machines
IPC: G06C11/00
Filed: 1923-03-09
Abstract: 218,961. Puttemans, H. A., and PerpÞte, G. V. L. March 9, 1923. Adding-machines with operating-means.-In a single-bank machine, the operations of recording the item set up by the keys, transmitting this item to the totalizer by re-setting the itemprinting wheels, and performing the necessary transfer actions, are effected by reciprocating a slide arranged on the top of the casing in such a position that it may be moved by the operator's thumb without the hand leaving the keyboard. Depression of the keys, disposed on the right hand end of the machine differentially and successively actuates the item-printing wheels 3' - - 3<9> through a master pinion, the wheels being embraced by. a frame successively stepped to the left by any suitable means. The number having thus been set up, a slide 16 mounted to slide along the top plate of the machine and provided with a thumb piece 24 carried by a blade spring 23 is moved to the right. A roller 22 on the slide consequently effects printing of the item by causing a spring-controlled frame 27 supporting the impression roller 14 to advance. The teeth 19 on the rack gear with a wheel 30 connected by gearing 6 with a square shaft 4 supporting a cylinder disposed within the item wheels 3. The rotation of the shaft and cylinder effects, through lugs on the cylinder and on the internal periphery of the wheels, the restoration of the latter to normal position and the transmission of the values standing on them to the totalizer wheels. In this movement of the slide also the frame embracing the item wheels is released to return to normal position. When the operator releases the slide it returns to the left under the action of a spring 33 wound up by gearing 18, 32 and in so doing it reverses the cylinder to bring its lugs again into zero position, and through any type of mechanism effects the necessary transfers.

Title: Improvements relating to the reduction of the angle-modulation of amplitude-modulated oscillations
Inventor: LEYTON ERIC MCPHAIL
IPC: H03C1/04
Filed: 1949-05-03
Abstract: 661,603. Radio signaling; modulating systems. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 25, 1950 [May 3, 1949], No. 11744/49. Class 40 (v). Undesired angle modulation is removed from amplitude-modulated oscillations of frequency FC by mixing them in a modulator 1 with constant-frequency oscillations FL from a source 2, selecting the sum (or difference) frequencies by a filter 3 and passing them, if desired, through a limiter 4, to a second modulator 5 when they are again mixed with the modulated oscillations FC. From the output, the difference (or sum frequency FL, selected by a filter 6, bears the original amplitude modulation without the undesired angle modulation. To avoid distortion, the modulators 1, 5 should give a linear relation of output to input. If the modulators are non-linear, distortion is reduced by the provision of the limiter 4, or by arranging that the input from source 2 to modulator 1 is of small amplitude compared with that of the oscillations FC, and that the input from the filter 3 to the modulator 5 is large compared with the oscillations FC. The Specification states that a single side-band input at FC (or an input with one side-band partially suppressed), is converted to a doubleside-band output at FL, and the system can therefore be used to prevent distortion that would otherwise occur in the reception of asymmetric side-band television signals.

Title: Improvements in and relating to automatic valves for fire extinguishing apparatus
IPC: A62C99/00
Filed: 1924-05-12
Abstract: 215,794. Huebner, H. May 11, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Sprinkling apparatus.-A gas outlet valve for fire-extinguishing apparatus using gas as the extinguishing medium is operated by a differential piston having a small space between it or its casing to connect the pressure on the two s'des. If there is a fall of pressure on the upper, larger side of the piston m due to the fusing of a closure or the opening of a hand-operated valve in a pipe network connected to a channel h, the pressure below the piston being unable to escape sufficiently quickly between the piston and its casing, forces the piston up, thus raising a valve b in the gas passage a, c. To restore the piston and valve to its closed position and to fill the pipe network gas is introduced through a valve k.

Abstract: 553,263. Sub press mechanism. LESLIE, F. H. Aug. 24, 1942, No. 11892. [Class 83 (iv)] Sub press mechanism for use in drawing or punching comprises a base member and an upper member connected at the end remote from the punching zone by a spacing block. The upper member that carries the punch is attached to a reinforcing member to limit deflection under the action of the press mainly to a narrow zone of the member remaining unreinforced adjacent to the spacing block. In a modification the base 10 is bolted to the upper member 26 offset at 28 and weakened at 36 to provide a flexure zone substantially in the plane of the top of the die 34. To permit the mounting of standard punches as at present used in sub press mechanism the fixing stem or shank 32 is received in a slot in the member 26 and clamped by a filling piece 46 bolted on at 50. In a further modification the part 28 is replaced by a separate rigid Z- shaped member bolted to the top plate and to a flexible member bolted by a cap piece to an upstanding block on the base.

Title: Improvements in and relating to solvent extraction apparatus
IPC: G01N25/14
Filed: 1944-06-23
Abstract: 578,111. Solvent extraction apparatus. WILKS, K. H. June 23, 1944, No. 12014. [Class 81 (i)] A solvent extraction apparatus comprises a condenser 1, extraction vessel 2 containing a filtering device 3, syphon tube 5 and hot solvent tube 6, the two latter terminating in the still 4 but the end of tube 6 being above the end of tube 5. A non- return valve in the tube 5 prevents passage of liquid therethrough from the still. In operation, sufficient solvent is introduced into the apparatus to fill the syphon tube 5 and to bring the level of liquid in the still above the bottom of tube 6 by an amount corresponding to the volume which is to be allowed to collect in the bottom of the extraction chamber 2. The solvent is boiled in the still 4 and the vapour pressure forces liquid from the still, up the tube 6, into the filtering device, vapour passing to the condenser. The solvent, after extracting the solute in 3, drains through to the lower part of vessel 2; when the fall in liquid level in the still exposes the end of tube 6, the pressure in the still is released, the syphon operates and liquid from the bottom of 2 is evacuated into the still. The cycle of operations is then automatically repeated until the solvent becomes saturated, when it may be drawn off and fresh solvent added. Specification 568,192 is referred to.
